I have the same display problem for my 13” Macbook pro that I bought in late 2016. I agree with all the comments state that this is clearly a product defect and degradation of Apple products. I already went to Brea Mall Apple store and tried to find out what happened, the only solution I got is to pay $400 for replacing a new display if your warranty is out. The thing is even though I am seeing enough reports online, Apple repair team did not see enough data to recognize this is a known issue that they should acknowledge and do something about it. I urge everyone who run into the problem go to Apple support site and log a ticket. I am in the process of escalating it upward and hoping to get a more satisfying resolution by talking to the senior product support staff and customer relation.
